Hotelling's model has been used to describe differentiation in the political "market." Suppose that 100 voters are evenly distributed between the extreme left and the extreme right on the political spectrum, and that all voters vote, and they always vote for the candidate closest to them on this spectrum. The numbers on this spectrum represent the number of voters lying to the left of the number. So, at the midpoint, fifty voters lie to the left and fifty to the right. At the extreme right end, all 100 voters lie to the left. 
To an economic naturalist, this model helps explain why political candidates:
A. are loyal to their political parties.
B. work to bring federally funded projects to their home districts.
C. move toward more centrist positions during campaign season.
D. take more extreme positions than are held by the general population.
